Electric Dipole Equations in Very-Near-Field Conditions for Electromagnetic Shielding Assessment-Part II: Wave Impedance, Reflection, and Transmission
This paper analyzes, in a quantitative way, the properties of the spatial distribution at the interface of the wave impedance as defined by Schelkunoff, in order to understand if and under which assumptions his transmission line theory for the evaluation of the shielding effectiveness can be used in the near-field region of a radiating electric dipole. The spatial distribution of the wave impedance and the reflection, and transmission coefficients are computed by the analytical formulation developed in Part I, and compared to those computed by an accurate 3-D full-wave model.
